The Compute Module 3 (or CM3) is a shrunk down version of the Raspberry Pi3 designed for use in industrial and commercial appliances. Its small form factor is the perfect candidate for a handheld. Although there are many homemade and commercial handhelds available that contain the full size RPi3 board, they tend to be very chunky and can have a somewhat “made in the garage” feel to them. We’re definitely not spoiled for choice when it comes to Compute Module handhelds, although I have covered two on this blog previously in the form of the FreePlay CM3 and Creoqode’s Lyra.
The Raspberry Pi Compute Modules have never gotten much love from manufacturers of obscure handhelds. In many ways they’re the perfect candidate for driving these things – the software is already there, the developer community is large and active and best yet, it’s almost guaranteed that a substantial hardware improvement will be released once every few years.
